PORTABLE HOSE BRIDGE Filed June 25, 1931 l l l l t ATTORNEYS Patented Dec. 29, 1931 UNITED STATES GUSTAVUS L. DAY, OF MENDI-IAM, NEW JERSEY PORTABLE HOSE BRIDGE Application filed June 23,

The. object of my invention is to provide improvements in hose bridges designed to be used in pairs for permitting vehicles to pass over the hose without injury thereto, said bridges comprisingarches having end and side flanges, the bridges being provided with means for preventing them from creeping on the roadway and the arches being provided with traction surfaces to prevent the tires of the vehicle wheels from slipping when passing over the bridges.

Practical embodiments of my invention are represented in the accompanying drawings in which:

Fig. 1 represents a top plan view of one of the hose bridges showing one embodiment thereof; the outer surface of the arch in this embodiment being shownas roughened to provide a traction surface;

Fig. 2 represents a longitudinal vertical section taken in the plane of the line II--II of Fig. 1, looking in the direction of the arrows; one pair of hose recesses being shown to accommodate one hose therethrough;

Fig. 8 represents a transverse vertical section taken in the plane ofthe line III-III of Fig. 1, looking in the direction of the arrows;

Fig. 4 represents a bottom plan view of the bridge;

Fig. 5 represents a top plan view of a modified form of bridge in which the arch is perforated to produce a traction surface;

Fig. 6 represents a longitudinal vertical section taken in the plane of the line VI-VI of Fig. 5, looking in the direction of the arrows; two pairs of alined recesses being shown for accommodating two fire hose;

Fig. 7 represents a top plan view of a third embodiment of my invention in which the arch is perforated and the outer surface of the arch is roughened to provide a traction surface; and

Fig. 8 represents a longitudinal vertical section taken in the plane. of the line .VIII VIII of Fig. 7 looking in the direction of the arrows; three pairs of hose recesses being shown for accommodating three hose.

arch 1 having horizontally disposed end flanges 2, 3 and vertically disposed side flanges 4:, '5. In the form illustrated in Figs. 1 to 4 inclusive, I have shown one pair of recesses 6 through the side flanges for ac-' commodating one hose Ttherethrough. In

this form I have shown the outer surface of I the arch 1 as roughened to provide a tract1on surface, while in the form illustrated 1n F lgs. 5 and 6 I have shownthe arch as 'per- Iforated to form a traction surface, the perthe bridge.

The means for preventing the bridge from creeping on the roadway may be bottom pro- JGCtlOIlS 9, produced by depressions formed in theouter surfaces of the horizontally disposed end flanges2 and 3.

It will be seen that in all of the forms the vertical side flanges 4 and -5 of the bridge have their bottom edges located substantially in the plane of the bottoms of the end flanges 2 and 3 so that great strength is imparted to the arch 1 and at the same time the bridge will be light, strong and inexpensive, and 85 readily portable.

It is evident that various changes may be resorted to in the construction, form and arrangement of the several parts without departing from the spirit and scope of my invention, and hence I do not intend to be limited to the particular embodiments herein shown and described, but

What I claim is 1. A hose bridge comprising an arch having end and side flanges, the arch being perforated to provide a traction surface.

2. An integral sheet metal hose bridge stamped out to form an arch having end and 109 side flanges, the arch being perforated to provide a traction surface.

3. A hose bridge comprising an arch having end and side flanges, the arch being per- 5 forated and the outer surface of the arch being roughened to provide a traction surface.

4. An integral sheet metal hose bridge stamped 'out to formian arch-having end and side flanges, the arch being perforated and the outer surface of the arch being roughenedto provide a traotionsur face.

5. A hose bridge comprising an arch having end and side flanges, the endvflangesbeing provided with bottom projections to prevent the bridge from creeping;

6. An integral sheet metal. hose bridge stampedoutito form an arch having end and side. flanges, portions of theend flanges being" depressed to form b'ottom' projections for preventing the bridge from creeping.

7. A hose bridgecomprising anarch having endandside flanges, thearch being provided with a traction surface and the end flanges being provided withbottom projections to prevent the bridgefrom-creeping.

8. An' integral sheet metal hose bridge stampecboutto form anarch'having end and side flanges, the arch being provided with traction surface and portions of' the end 21 flanges beingdepressedxto form projections for; preventing the" bridge form creeping.

9. .A' hose bridgecOmprising an arch having end andside' flanges, the arch bein provided with a traction surface roughened lthronghontt for preventing both longitudinal andlalteral' slippage'of the wheel tires when passing over the same;

10. An integral sheet metal hose bridge stampedout to form an arch having end and 40 side flanges, the' arch'being'provided with a traction surface roughened.throughout for preventing both longitudinal'and lateral slippage'of'the wheeltires when passing'over the same,

Intestimony, that I claim the foregoing as my. invention l'have signed my namethis 22nd day of June, 1931';
